Boeing 747g

NASA X-47g

The first badass airplane photo in history, of an Airco DH.4 (1918)

The first hybrid, the Taylor Aerocar (1949)

A King Air 100-- what Charlie had to land in TWICE A SPY with no piloting experience save PlayStation. I hope whoever took this photo got out of the way.

DARPA's ISIS

DARPA's ISIS, a 450-foot unmanned spy blimp that shoots hypersonic missiles from 12 miles up, where it can stay for 10 years, out of range of most surface-to-air or air-to-air missiles. Probably corners well, too. What will happen to conventional warbirds?
